WordNet RDF/OWL Files

List of files and explanation

Princeton WordNet is a lexical database for the English language [Fellbaum, 1998]. In [WordNet in RDF/OWL, 2006] a conversion of WordNet to RDF/OWL is presented. The files that constitute the actual conversion are listed below.

Downloadable files

The conversion is created with a Prolog program. The source code contains instructions for use. The conversion program makes use of the open-source SWI-Prolog and its Semantic Web library.

As described in [WordNet in RDF/OWL, 2006] there are two versions available of the conversion: Basic and Full. An archive file for both Full and Basic versions are available from the following location: http://www.w3.org/2006/03/wn/wn20/download/.

Alternatively, for each version one can select only those files that are necessary for a particular application. For example, it is possible to use the Full version with only the hyponym relation and exclude the other relations.

WordNet 2.0 Full consists of the following three files plus any of the files that contain relations that are listed below.

• WordNet Full Schema
• Synsets
• WordSenses, Words, instances of properties that connect Synsets, Words, WordSenses

WordNet 2.0 Basic consists of the following files plus any of the files that contain relations between Synsets

• WordNet Basic Schema
• Synsets
• senseLabels

Files that contain relations between Synsets:

• hyponymy
• entailment
• similarity
• member meronymy
• substance meronymy
• part meronymy
• classification
• cause
• verb grouping
• attribute

Files that contain relations between WordSenses:

• derivational relatedness
• antonymy
• see also
• participle
• pertains to

Files that provide information on Synsets:

• glosses
• frames

Source files

The following source files used to perform the conversion are listed below:

• WNprolog-2.0.tar.gz, the original Prolog distribution of WordNet 2.0
• WordNet-2.0.tar.gz, the custom format distribution of WordNet 2.0
• sen.pl, additional constructed source file for the frame sentences that are missing in the original Prolog distribution
• frames.vrb, the source file from the custom format distribution, used to create sen.pl
